Which formulations are dry, finely ground and usually must be mixed with water for application, easily stored, and require constant agitation, while being abrasive to pumps and nozzles?

Which formulations are dry, finely ground and usually must be mixed with water for application, easily stored, and require constant agitation, while being abrasive to pumps and nozzles?

• A. Wettable Powders
• B. Dusts
• C. Flowables
• D. ULV

Answer: (A)

Wettable powders are dry, finely ground pesticide formulations designed to be dispersed in water to form a uniform suspension. Because the particles are tiny, they tend to settle quickly, so constant agitation is needed during mixing and throughout application to keep the suspension even. The abrasive nature of the solid particles means pumps and nozzles can wear or clog if the mixture isn’t properly formed or kept in motion. They store as dry powders, which makes handling convenient, but the mixing process must be done correctly to avoid settling, clumping, or clogging. Dusts share the dry, powdery form but are typically used in dry applications rather than being dispersed in water, so they don’t fit the “must be mixed with water for application” part. Flowables are not dry; they are suspensions of solids in a liquid and require mixing, but they aren’t described as dry formulations. ULV products are concentrated liquids used for ultra-low-volume spraying and aren’t dry powders either.
